Slow website; what's your take on this?

And then?

You're actually looking pretty darn good right here, in this test using IE 10. Only a couple of F grades, easy fixes.

Thanks for your reply. I thought a CDN would make the website quicker since, after all, the geographic distance should be less for non-European visitors in my case.

I'm not sure if dropping CloudFlare in my situation is also the best idea, since the original webserver might not be quick enough. For example, if I disable CloudFlare the performance is much worse:

From Chicago: http://www.webpagetest.org/result/140406_TK_5KR/
From Moscow: http://www.webpagetest.org/result/140406_BE_5M0/

Slow first byte time is going to be shared hosting every time, and is going to be a oversold overcrowded machine at the host, every time. AND IT IS SIMPLE TO PROVE to your host - simply create a simple HTML page with nothing but the words "Hello There" and watch the TTFB STILL be bad for testing just that page!

Thanks for the TTFB measurement suggestion. With CloudFlare disabled:

Thank you; added to the file.

Rename it to match, upload to overwrite. I compressed it for you, shaving off 14kb.
Thanks; replaced.

Thanks for your reply. I looked into MaxCDN, but they do not, in comparison to CloudFlare and Incapsula, offer entire page caching (unless you're an enterprise).

Wouldn't that negatively impact the website speed for non-European visitors, since I have only a few small images and one css file that can be served by MaxCDN. The page itself would still need to be served from the webserver in Europe, giving slow DNS and TTFB times for non-European visitors?
